Not using it with a harmony, but did you first set up the flirc via its accompanying setup program?
Also see the ropieee-guide-for-beginners, as in following screenshot …
I’m out of ideas @Trent_Reynolds
Let me move the topic to the appropriate Ropieee category and ping Harry, the developer (@spockfish), while you click the feedback button in the Ropieee web interface’s Advanced tab and then post the identifier for him to correlate.
Just to be sure, the entry in the field “Roon Control Zone” in the Remote setup section of RoPieee needs to match the name of the playback zone in Roon as specified in Roon Settings > Audio.
Judging from the Screenshot the specified name corresponds to the hostname of the RoPieee device - this might be same name you’re using for the playback zone, but doesn’t have to be.
